Lake - experiment for an un - baffled practical circular array verified the effectiveness and error tolerance of this new method . 5 . the intrinsic mechanism of optimal array gains is studied for the scenario when the element spacing is less than one half - wavelength , with emphasis on un - baffled circular arrays 針對(duì)一個(gè)24元均勻分布圓陣的湖上實(shí)驗(yàn)結(jié)果表明,這種新的恒定束寬波束形成方法是有效的,且在一般條件下,對(duì)基陣陣元幅度和相位響應(yīng)誤差具有良好的寬容性。
